I have been searching for hours on the forum and found nothing on a MB part number that is a direct bolt-on 74mm TB. Is this true? I read some guys buying from tvt but they no longer in. Anything helps thx.

 

I will send you the direct bolt on and plug in part number in a second. let me go find it

 

Let me know if you need help finding one, I found a couple locally last time I looked.

Mercedes Part # A1131410125
Bosch Part # 280750017

 

Which MB cars is that throttle body from?

BC.

 

I think its 02-05 S class, CL and others with the m113 v8.

 

I assume you would need an aftermarket CAI such as the NeedsWings rig or a stock MB airbox and larger diameter tubing?

 

i have been thinking of changing mine also.
please post the outcome of your project, ie how difficult to do, performance improvement, ect.
also where you find the part.
thanks

I haven't done this mod but from what I've read the TB coupled with a quality CAI (I believe the NeedsWings is the only quality CAI for the x-fire) will give you a nice boost...maybe 5 to 10 hp. (?). TB's are very easy to install. Usually 2 or four bolts depending on the engine.

 

...4 bolts and 1 plug... here is a pic of the stock TB and the 74mm TB

 

I got one for my dual system on ebay and they are easy to plug and play with. Ebay wins again, Woody

 

So can someone confirm...the 74mm does not work with the stock airbox without modification? Would there be any benifit using the 74mm with a stock airbox vs NeedsWings CAI? Does the ECU adapt without error?

Thanks.
